I don't believe you have to know someone in order to want them to have a great life. But mostly its because I understand how you feel, and I know that you can get through it. It's hard, but its worth it to face the demons and try to build a life even when all you want to do is quit.
It's cliche to say this but, you can't let the evil doers win. And the best way to do that is to keep going, to be happy.
